We present a photometric catalog of infrared (IR) sources based on the NorthEcliptic PoleWide field (NEP-Wide) survey of AKARI, which is an infrared spacetelescope launched by Japan. The NEP-Wide survey covered 5.4 deg2 area, anearly circular shape centered on the North Ecliptic Pole, using ninephotometric filter-bands from 2 - 25 {\mu}m of the Infrared Camera (IRC).Extensive efforts were made to reduce possible false objects due to cosmic rayhits, multiplexer bleeding phenomena around bright sources, and otherartifacts. The number of detected sources varied depending on the filter band:with about 109,000 sources being cataloged in the near-IR bands at 2 - 5{\mu}m, about 20,000 sources in the shorter parts of the mid-IR bands between 7- 11 {\mu}m, and about 16,000 sources in the longer parts of the mid-IR bands,with \sim 4,000 sources at 24 {\mu}m. The estimated 5? detection limits areapproximately 21 magnitude (mag) in the 2 - 5 {\mu}m bands, 19.5 - 19 mag inthe 7 - 11 {\mu}m, and 18.8 - 18.5 mag in the 15 - 24 {\mu}m bands in the ABmagnitude scale. The completenesses for those bands were evaluated as afunction of magnitude: the 50% completeness limits are about 19.8 mag at 3{\mu}m, 18.6 mag at 9 {\mu}m, and 18 mag at 18 {\mu}m band, respectively. Toconstruct a reliable source catalog, all of the detected sources were examinedby matching them with those in other wavelength data, including optical andground-based near-IR bands. The final band-merged catalog contains about114,800 sources detected in the IRC filter bands. The properties of the sourcesare presented in terms of the distributions in various color-color diagrams.
